Abstract
The utility model discloses an aluminum electrolytic capacitor with foil, comprising aluminum shell, guide pin, guide pin is negative, electrolytic paper, anode foil and the cathode foil, with the guide needle and the anode foil with a foil, with the negative guide pin and a cathode foil with a foil, the foil with positive, negative guide pin guide pin, electrolytic paper, anode foil and the cathode foil winding into the core. The utility model through the foil set in with the guide needle and the electrode foil, effectively prevent the burrs generated by the guide needle and the electrode foil riveted into direct contact with the electrolytic paper caused electrolytic paper is punctured, solve the resulting from thorn riveting hair spiked in electrolytic paper electrolytic capacitor short circuit breakdown phenomenon, because the guide needle and the electrode foil with cover foil, thus increasing the new current paths, the electrolytic capacitor can withstand the reverse voltage and higher temperature, prolong the service life of the electrolytic capacitor.
Description
Technical field
The utility model relates to a kind of capacitor, relates to specifically a kind of aluminium electrolytic capacitor with foliation.
Background technology
At present, existing aluminium electrolytic capacitor generally comprises a shell, and is arranged at sub-prime and in described shell and is arranged at Jiao Gai in described shell, and sub-prime stings respectively the capacitor guide pin of riveting on described anode foils and Cathode Foil by an anode foils, a Cathode Foil, at least one electrolytic paper and two and consists of.In actual processing, because capacitor guide pin directly stings riveting in Cathode Foil, this mode easily because of thorn during riveting magic flower produce burr, when reeling together with electrolytic paper, burr easily pierces through electrolytic paper, make electrolytic capacitor can produce spark phenomenon under the state that uses or switch on, easily cause the short circuit of electrolytic capacitor to puncture; The tongue of another cathode foil and guide pin is riveting knot by thorn, and during energising, this place electrochemical reaction will occur and produces a large amount of heat, and heat is accumulated in aluminium electrolytic capacitor, causes that easily the electrolyte in aluminium electrolytic capacitor is withered, finally causes aluminium electrolytic capacitor to lose efficacy.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the aluminium electrolytic capacitor with foliation of a kind of stable performance, long service life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of aluminium electrolytic capacitor with foliation, comprise aluminum hull, positive guide pin, negative guide pin, electrolytic paper, anode foils and Cathode Foil, the junction of described positive guide pin and anode foils is provided with a foliation, the junction of described negative guide pin and Cathode Foil is provided with a foliation, and this foliation can be wound into fuse with positive guide pin, negative guide pin, electrolytic paper, anode foils and Cathode Foil.
Preferably, described aluminum hull is electrically connected to negative guide pin by wire.
Preferably, described foliation is to paste by cold welding nail joint place that the mode of welding is welded in positive guide pin and anode foils and negative guide pin and Cathode Foil.
compared with prior art, the beneficial effects of the utility model are: the utility model arranges foliation by the junction at guide pin and utmost point paper tinsel, prevented that effectively the burr that the riveted joint of guide pin and utmost point paper tinsel produces from directly touching electrolytic paper and causing electrolytic paper to be punctured, solution is known clearly and is pierced through the phenomenons such as electrolytic capacitor short circuit that electrolytic paper causes punctures because of thorn riveting burr, because the junction at guide pin and utmost point paper tinsel covers foliation, therefore increased new current path, make electrolytic capacitor can bear reverse voltage and higher temperature, extended the useful life of electrolytic capacitor, effectively eliminated the defective of bringing because of thorn riveting burr in the aluminium electrolytic capacitor course of processing.The utility model structure is very simple, easily realizes.
